Even the average college football fan knows some schools are renowned for their tradition and some are not. That's why certain schools change uniforms every couple years, or even every game (I'm looking at you, Oregon).
Other schools like to stick to their roots and honor the past by keeping their uniforms untouched (generally). There may be a couple updates (stripes moved around, a patch for a bowl game, etc.), but that's about the extent of it. These are the schools that keep their storied histories alive on the field with their uniforms (and play).
